Definitions

  • the present invention relates to built laundry detergent compositions containing anionic sulphonate or sulphate surfactants and a textile softening clay, the compositions exhibiting increased mildness to the skin as well as improved textile softening properties.
  • Heavy duty laundry detergent compositions have for many years contained an anionic sulphonate or sulphate surfactant, for example, linear alkylbenzene sulphonate (LAS) or primary alcohol sulphate (PAS), as the principal detergent-active ingredient.
  • anionic surfactants are frequently used in conjunction with ethoxylated alcohol nonionic surfactants which give improved detergency on hydrophobic soils.
  • the nonionic surfactants generally have alkyl chain lengths of C 12 -C 18 and degrees of ethoxylation of 1 to 10.
  • anionic and anionic/nonionic surfactant systems are robust and highly efficient on a wide range of soils and under a wide range of conditions, for example, temperature and water hardness. However, they are not noted for mildness to skin. These materials are designed to interact with fatty materials like body soil and protein residues on soiled laundry, and can therefore interact with the skin to give reactions such as dryness and erythema (redness).
  • the milder surfactants used to formulate products intended for prolonged skin contact, for example, shampoos and shower gels would not perform adequately in heavy duty laundry detergent compositions because of insufficient interaction with fatty materials occurring as soil.
  • GB 2 020 688 discloses a high suds washing powder comprising an active blend of an anionic surfactant and a nonionic surfactant. Only one type of nonionic surfactant in combination with anionic surfactant is disclosed.
  • WO 94 16052A discloses high bulk density particulate laundry detergent compositions containing low levels (typically below 1 wt%) of a highly ethoxylated long chain alcohol, for example tallow alcohol 80EO, the benefit being improved dissolution.
  • EP 293 139A (Procter & Gamble) discloses detergent compositions enclosed in two-compartment sachets, the compositions exemplified containing low levels (0.2-0.8 wt%) of tallow alcohol 25EO.
  • WO 93 02176A discloses the use of highly ethoxylated aliphatic alcohols as "structure breakers" in high bulk density laundry detergent powders containing conventional ethoxylated alcohol nonionic surfactants.
  • WO 00 08129A discloses mild particulate laundry detergent compositions based on high-foaming anionic surfactant (for example linear alkylbenzene sulphonate) plus one or more milder cosurfactants, for example, amine oxide or cocoamidopropyl betaine.
  • high-foaming anionic surfactant for example linear alkylbenzene sulphonate
  • milder cosurfactants for example, amine oxide or cocoamidopropyl betaine.
  • Particulate laundry detergent compositions containing textile softening clays are widely disclosed, for example, in EP 299 575B (Procter & Gamble), EP 313 146B (Procter & Gamble), EP 383 828B (Novo Nordisk and Procter & Gamble), EP 495 258A (Procter & Gamble), EP 753 567A (Procter & Gamble) and EP 582 478B (Colgate-Palmolive).
  • the present invention provides a built particulate laundry detergent composition comprising
  • the present invention further provides the use of the combination of a highly ethoxylated alcohol nonionic surfactant having an average degree of ethoxylation of from 15 to 40 in an amount of from 0.5 to 5 wt% and a textile softening clay in an amount of from 0.5 to 5 wt% to increase the mildness to skin and textile softening effect of a built particulate laundry detergent composition containing an anionic sulphonate or sulphate detergent.
  • Detergent compositions of the invention contain a conventional anionic sulphonate or sulphate surfactant and a conventional nonionic surfactant, and also contain as essential ingredients a low level of a highly ethoxylated nonionic surfactant (iii) which is an aliphatic alcohol having an average degree of ethoxylation of from 15 to 40, and a low level of a textile softening clay (iv).
  • a highly ethoxylated nonionic surfactant iii
  • iv a highly ethoxylated nonionic surfactant
  • the invention is based first on the observation that use of a highly ethoxylated nonionic surfactant at low levels to supplement or replace part of a conventional anionic/nonionic surfactant system results in a measurable increase in mildness to skin.
  • the skin-mild detergent compositions of the invention are free of enzymes, since enzymes can also cause skin irritation to sensitive individuals.
  • enzymatic compositions are also within the scope of the invention.
  • Anionic sulphonate and sulphate surfactants are well-known to those skilled in the art. Many suitable detergent-active compounds are available and are fully described in the literature, for example, in "Surface-Active Agents and Detergents", Volumes I and II, by Schwartz, Perry and Berch.
  • alkylbenzene sulphonates examples include alkylbenzene sulphonates, primary and secondary alkylsulphates, particularly C 8 -C 15 primary alkyl sulphates; alkyl ether sulphates; olefin sulphonates; alkyl xylene sulphonates; dialkyl sulphosuccinates; and fatty acid ester sulphonates.

  • the alcohol may be derived from natural or synthetic feedstock.
  • the highly ethoxylated alcohol nonionic surfactant is a solid at ambient temperature, so that it may conveniently be incorporated in the compositions of the invention in the form of separately admixed granules. Because these materials are solid, no carrier material is required in the granules: especially preferred granules are substantially 100 wt% pure and have a particle size within the range of from 100 to 1000 micrometres.
  • the chain length is preferably at least C 16 , more preferably from C 16 to C 18 .
